Definitions

  • the invention relates to a device for measuring flow processes of fluids, an inlet, an outlet, a driven Verdrängergreater, which is arranged in a housing in which a displacement chamber is formed, in which at least one driven Verdrängerrad is rotatably arranged, wherein the displacement chamber via a first inlet channel to the inlet and via a first outlet channel to the outlet is fluidly connected, a bypass line through which the positive displacement counter is bypassed, a Druckdifferenzaufillon, which is arranged in the bypass line and an evaluation and control unit via which the drivable positive displacement counter in Dependence of the pressure difference sensor applied pressure difference is adjustable.
  • Such devices have been known for many years and are used, for example, for injection quantity measurement in internal combustion engines.
  • This electronically controlled flowmeter has a main conduit with an inlet and an outlet in which a rotary displacer in the form of a gear pump is arranged. Parallel to the main line runs a bypass line through which the rotary displacer is bypassed and in which a serving as Druckdifferenzaufêtender piston is arranged in a measuring chamber. To determine the flow rate, the deflection of the piston in the measuring chamber is measured by means of an optical sensor. The speed of the gear pump is continuously readjusted due to this signal via an evaluation and control unit, in such a way that the piston always returned to its original position, so that only small currents arise in the bypass line. From the measured via an encoder number of revolutions or partial revolutions of the gear pump and the known delivery volume of the gear pump in one revolution so the flow is calculated within a predetermined time interval.
  • Such a constructed flow meter is also in the DE 103 31 228 B3 disclosed.
  • the gear pump is set to a constant speed before each injection, so that subsequently the movement of the piston is measured and this deflection is used to determine the injection curves.
  • a pressure sensor and a temperature sensor are arranged in the measuring chamber, the measured values of which are likewise fed to the arithmetic unit for calculating and correcting the injection quantity profiles.
  • the occurring wear in the region of the displacement wheel opposite the inlet opening can be significantly reduced be achieved because a much more uniform load of the positive displacement wheel over its axial extent is achieved.
  • the filling of the displacement chamber takes place correspondingly from both axial sides, whereby the number and intensity of the occurring pressure surges are reduced at the same solid surface of the displacer.
  • the first drainage channel preferably opens into the displacement chamber via a first outlet opening and a second outlet channel opens into the displacement chamber via a second outlet opening on the rear side. Accordingly, a one-sided load of the positive displacement is prevented by the cavitation and counteracted according to a progressive Kavitationsfrrien by axially unilateral load on the pressure side of the positive displacement, in which there is a higher load due to the higher delivery pressure.
  • the housing is designed in two parts, wherein in the first housing part, the displacement chamber is closed, which is closed by a second housing part in which the frontal inlet opening and / or outlet opening is arranged and in which a measuring chamber of the pressure difference sensor is arranged.
  • the first housing part the displacement chamber is closed, which is closed by a second housing part in which the frontal inlet opening and / or outlet opening is arranged and in which a measuring chamber of the pressure difference sensor is arranged.
  • the inlet openings and / or the outlet openings are kidney-shaped on the front side and on the rear side of the housing delimiting the displacement chamber, whereby a uniform filling of the pump chamber is achieved with a marked reduction in the pressure surges that occur.
  • the positive displacement meter is designed as a gear pump and the kidney-shaped inlet openings and / or outlet openings extend radially outward to the tooth roots of the positive displacement, whereby pressure surges and resulting cavitation are additionally reduced and the filling of the displacement chamber is improved.
  • the inlet opening and / or the outlet opening on the front side of the displacement chamber is designed mirror-inverted to the inlet opening and / or to the outlet opening on the rear side of the displacement chamber.
  • a particularly simple supply line without further connections results when the first inlet channel and the second inlet channel and / or the first outlet channel and the second outlet channel are fluidically connected to each other via connection channels arranged in the housing and both inlet channels and / or both outlet channels fluidly with the common Housing formed inlet and / or outlet are connected.
  • the number of external lines is thereby limited to a necessary minimum, whereby the assembly is simplified.
  • the inlet openings and / or the outlet openings are milled into the displacement chamber on frontally and rearwardly delimiting walls. These walls are easily accessible, so that a cost-effective production of the openings by milling is possible.
  • a bush is arranged in the first housing part, which forms the displacement chamber and which is inserted into a corresponding receiving opening of the first housing part.
  • the second inlet channel and the second outlet channel are at least partially formed in the wall which bounds the displacement chamber on the rear side and on the radially delimiting outer wall of the socket.
  • These channels can be made through easy-to-drill holes in the walls. Compared to a formation of the channels in the first housing part, the closing by additional plugs or the like is not required. Instead, a seal of these channels can be done by simple interposition of Axialdichtringes between the housing parts and the socket, whereby the assembly is significantly simplified.
  • a particularly advantageous development of the invention results from the fact that grooves are formed on the radially outer side of the radially delimiting outer wall of the bush, which form a portion of the second inlet channel and the second outlet channel, which are closed radially outwardly by the first housing part. These grooves can be milled and form a particularly simple fluidic connection between the end face and the back of the displacement chamber for supplying this chamber with fluid on both sides.

  • a displacement sensor is arranged, which is in operative connection with the piston and in which by the deflection of the piston, a dependent on the size of the deflection voltage is generated.
  • This displacement sensor attached to the measuring chamber 44 is, in particular, a magnetoresistive sensor, by means of which the field strength of a magnet acting on it is converted into a voltage. As displacement sensors and light sensors can be used.

  • the determination of the flow rate at the piston takes place, for example, by the deflection of the piston being differentiated in the evaluation and control unit, which is connected to the displacement sensor, and then multiplied by the base area of the piston, so that a volume flow in the bypass line 42 in FIG this time interval results.
  • the flow through the positive displacement counter 14 can either be determined from the determined control data or calculated via the rotational speed, if this is measured directly at the positive displacement counter 14 or at the drive motor, for example via optical encoders or magnetoresistive sensors.
  • the cavitation load in the displacement chamber 36 and the displacement wheel 64 decreases markedly and the positive displacement counter 14 thus remains much longer lasting. This increases the accuracy of the measurement results, since each revolution of the displacement counter 14 must be assigned a volume flow, which would change in the course of operation in case of excessive wear due to additional cavities. Another advantage results from the interchangeability and free choice of material of the socket.
  • the invention is not limited to the embodiment described, but various modifications are possible within the scope of the main claim.
